The Giants' Graves are the remains of two Neolithic chambered tombs on the Isle of Arran. They are situated within 40 metres of each other, and stand on a ridge 120 metres above the sea in a clearing in a forest, overlooking Whiting Bay to the south.
The northern cairn has been much robbed, but the edges are still well-defined. The chamber is 6 metres long, and around 1 metre wide. It was excavated in 1902, and among the artifacts recovered were pottery shards, flint knives, and leaf-shaped arrowheads.
The southern cairn is at right angles to the larger northern cairn. The chamber is about 4 metres long, and over 1 metre wide. Excavations in 1902 only revealed soil and stones, however in 1961-1962 further exploration produced nine sherds of a round-based vessel, and fragments of burnt bone.
References:Visby Cathedral (also known as St. Mary’s Church) is the only survived medieval church in Visby. It was originally built for German merchants and inaugurated in 1225. Around the year 1350 the church was enlarged and converted into a basilica. The two-storey magazine was also added then above the nave as a warehouse for merchants.
Following the Reformation, the church was transformed into a parish church for the town of Visby. All other churches were abandoned. Shortly after the Reformation, in 1572, Gotland was made into its own Diocese, and the church designated its cathedral.
There is not much left of the original interior. The font is made of local red marble in the 13th century. The pulpit was made in Lübeck in 1684. There are 400 graves under the church floor.
